136' it known that I, CARL H. BISSELL, Syracuse, in the county of Onondaga and State of New York, have invented a new Electric Lamp Socket, of which the following is a specification. v i

My" invention has for its object the pro duction of an incandescent electric lamp particularly simple and compact in construction and is composed of a minimum number of parts; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure l is an elevation, partly in section,

of this electric lamp socket. Fig. 2 is a top plan of the socket, theouter shell being removed. Fig. 3 is an invertedplan of parts seen in Fig. 2. Figs. t and 5 are sectlonal views taken, respectively, on lines A-A Figs. 6 and 7 are ele- Figs. 2 and Figs. 8 and 9 are detail views of terminals of the socket. i

1 isthe. base of this incandescent lamp socket, thebafse being composed of any suitable insulating material and being formed with a recess including a slot-like portion 2 extending through diametrically opposite sides and through one end face thereof, the recess having an enlargement 3 of the portion 2, the enlargement opening through said end face and laterally through another 'side portion of thebase. The base is also formed-with a lengthwise recess or groove 4 this groove opening through the end face of the base through which the recess opens and being closed at its opposite end byla wall.5. I

terminals supported by. the base, the terminal 6 being located in the .6 and 7 arewire groove 8 formed in'the side of the base 1 and opening into. the slot-like portion 2 of the recess through the top thereof as best 'seen inFig. 5. Said terminal 6 is also provided with a portion as 9 extending into the slot 2 and lying close to the end wall of the slot, and with an integral extension ld-projec't-ing laterally from the portion 9 (if-the terminal 6. This extension 10 proof ther'ccess and is provided with a shelf portion 11 of 1 extending parallel to and opposed'to the top or inner end wall of such enlargement 3 for retaining the key in position as hereinafter-explained. The terminal 6 is held in position by a fastening member as a screw 12 inserted through the upper end of the base and extending lengthwise of the base and into a perforation 13 formed in the extension 10. provided with a binding screw 14 which threads into the perforation 15 in the portion of the terminal 6 lying in the groove 8.

The terminal 7 is located in the groove 4 V and is provided with angular extensions 16 and 17 at its. opposite ends, the extension 16 projecting across the end of the base hrough which the recess opens, and constituting the inner terminal for engaging the central terminal of the lamp. This extension'projects into the sleeve terminal 18 which engages the outer terminal of the lamp. The other extension 17 is bent outwardly relatively to the axis of the base and terminates in a part which projects inwardly relatively to said axis and engages the wall 5 at the inner end of the groove 4; and the terminal 7 is secured tothe base by a fastenin member as the screw 19 extending lengthwise of the base through the wall 5 and into a perforation 20 at the inner side of the outwardly bent portion of the The terminal 6 is also,

end of the base witha head 23 at its end'contiguons to the end of the base 22 are passed, a portion of'this head extending across and closing the enlargement 3 of the recess 2.

7 24 is a switch through which the circuit to the terminal 18' is made and broken, said switch being arranged to break the circuit at two points and being here shown as con; sisting of a substantially U-shaped spring secured between its ends to the base by a screw 25 extending into the top or inner end wall of the recess 2 and threading into a nut 26 embedded in the base from the rear end thereof. One arm of this spring is movable through which the screws g2 resales.

into and out of ontact with the terminal 6 tween-one of the wire terminals and one of andparticularly the portion 9 thereof, and the lamp contact terminals, theswitch comthe other arm ofsuch springis movable iiito prisin iii-substantially U-shaped' spring seand out of contactwith the head 23 of the cured between its ends to the base and havsleeve terminal 18.

My incandescent electric lamp socket is particularly advantageous in that one of the wire terminals and one of theterminals' for engagingthe lamp terminals are formed integral and can be stamped in one operation and further infthat the switch makes contact directlywith the sleeve terminal so and is arranged iii a particularly simple manner to break at, two points thus provld ing for a simple and compact assembly of the parts of the socket. 'The fcompactness of the lamp; socket is furtherenhanced by the factpthat the key for operating theswitch is," held in; position comprisingan insulating base formed with a recess opening through one end thereof, 7
